移除书签Choose Your Tools with Care
Applications grow in size, complexity, and sophistication, while the time available to develop them grows shorter. It makes better use of developers’ time and intelligence if they can concentrate on writing more business-domain code and less infrastructure code.
Widely used components and frameworks are likely to have fewer bugs than the ones developed in-house.
However, choosing the right mix of tools for your application can be a tricky business requiring some thought. In fact when making a choice, there are a few things you should keep in mind:
Different tools may rely on different assumptions about their context — e.g., surrounding infrastructure, control model, data model, communication protocols, etc. — which can lead to an architectural mismatch between the application and the tools. Such a mismatch leads to hacks and workarounds that will make the code more complex than necessary.
Vendor lock-in occurs when code that depends heavily on specific vendor products ends up being constrained by them on several counts: maintainability, performances, ability to evolve, price, etc.
Licensing terms matter, even for free software. For example, in some companies it is not acceptable to use software licensed under the GNU license terms because of its viral nature — i.e., software developed with it must be distributed along with its source code.
